    Habit
    Perennial; caespitose; clumped loosely. Culms 32-155 cm long; 1 -noded. Culm-internodes glaucous; smooth; distally glabrous. Lateral branches sparse. Leaf-sheaths longer than adjacent culm internode; smooth, or scaberulous; glabrous on surface. Leaf-sheath oral hairs pubescent; 0.3-1.1 mm long. Ligule a fringe of hairs; 1 mm long. Collar glabrous. Leaf-blades curled; 15-30 cm long; 2.3-4.5 mm wide. Leaf-blade surface scabrous; rough adaxially.
    Inflorescences
    Inflorescence a panicle. Panicle contracted; lanceolate; equilateral, or nodding; 13-40 cm long; 1.5-4 cm wide. Primary panicle branches appressed; 4 -nate; 4-8 cm long; bearing spikelets almost to the base. Panicle branches smooth, or scaberulous. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 9-18.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 0.9-1.5 mm long; pubescent; acute.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 9-18.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 0.9-1.5 mm long; pubescent; acute.
    Glume
    Glumes deciduous; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 9-18.5 mm long; 1.4 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface smooth to scabrous. Lower glume apex emarginate; mucronate. Upper glume lanceolate; 6.4-13 mm long; 1.4-1.7 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex emarginate; mucronate.
    Florets
    Fertile lemma lanceolate; subterete; 3.7-9 mm long; coriaceous; pallid and light brown; without keel; 3 -veined. Lemma surface smooth, or scaberulous; rough above. Lemma margins involute; covering most of palea; without distinctive roughness, or tuberculate (along groove). Lemma apex acute; awned; 3 -awned. Principal lemma awn pseudo-articulate at base; with 14-46 mm long limb; without a column; persistent. Lateral lemma awns 11-40 mm long; subequal to principal, or shorter than principal. Palea 0.2 length of lemma; without keels.
    Flowers
    Anthers 3.
    Fruits
    Caryopsis with adherent pericarp; sulcate on hilar side; 3.1-7 mm long. Hilum linear; 0.4-0.5 length of caryopsis.
